[The significance of digital subtraction angiography in diseases of the lungs and mediastinum].

The authors present their first experience with lung DSA in a group of 75 patients. The examination was most frequently performed by instilling a contrast medium into central, less frequently into peripheral veins. The most frequent indications included tumorous lung diseases and mediastinal tumours before an operation treatment, a suspected pulmonary embolism, lung and vascular malformation. Intravenous DSA proved to be also useful in the evaluation of pathological changes of thoracic aorta.
